Words including "Jude Raus" — German for "Jew Out" — and "Hitler Good!" in English, were found in red paint Saturday on a large monument at the former Plaszow camp near Krakow. A smaller memorial plaque was also painted with a swastika and "Jude Raus."
The vandalism was discovered a day before a planned memorial march marking the 67th anniversary of the liquidation of Krakow's ghetto.
On March 13, 1943, German soldiers started a two-day action in which they emptied Krakow's ghetto of its estimated 16,000 Jewish residents, shipping them to Plaszow and to the Auschwitz-Birkenau death camp.
The news agency PAP quoted a police official, Anna Zbroja, as saying authorities are on the spot trying to determine when the vandalism occurred.
The Plaszow camp featured in Steven Spielberg's 1993 Oscar-winning film "Schindler's List," which chronicled efforts by German industrialist Oskar Schindler to save Jews by having them work in his Krakow factory.
